HARROW.

SPECIFICATION forming part of Letters Patent No. 273,479, dated March 6,1883.

Application filed August 4, 1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM F. DODGE, of Bloomfield, in the county ofDavis and State of Iowa, have invented an Improved Harrow, of which thefollowing is a specification.

My invention relates to that class of harrows in which a frame carryingteeth is vertically adjustable relative to a base-frame, through whichthe teeth must extend to enter the ground.

It consists informing perforated ears integral with a metal plateadapted to be fixed to a wooden frame to serve as a bearing and cleaningdevice for the teeth, and also as a wearing-surface to protect the woodwhen the teeth are elevated, and the complete harrow dragged to scrapeand level the surface of the ground, or moved from one field to anotherin an inoperative condition.

Figure 1 of my accompanying drawings is a top view, and Fig. 2 aperspective view, of my harrow. Together they clearly illustrate theconstruction and operation of my complete invention.

A represents the lower frame, preferably made of wood, and V-shaped.

B represents the upper and suspended frame, corresponding in shape andsize with the lower, and carrying a series of fixed teeth, 1 2 3 4.These teeth are of triangular shape in crosssection, and are so set inthe frame that they will always present a sharp edge to the front, and aflat side against the lower frame whenever they comein contact with saidlower frame.

G G are flat metal plates, fixed on the under sides of the frame A. Eachplate has'a series of perforated ears or eyes, 5 6 7 8, formed integraltherewith, to project inward, immediately under the points of the teeth1 2 3 4, in such a manner that the points of the teeth will pass throughthem as the upper frame is lowered. (When the frame A is made of wood,staples may be fixed in the wood to projectinward in lieu of theperforated ears 5 6 7 8.)

d d are posts fixed to the sides of the frame A and connected withbracing-pieces f,

g g are compound levers, pivoted to the tops of the posts 01. The twopieces in each pair of levers are flexibly connected with each other,between the posts d, and with the upper frame,

B, at their ends, by means of -pivoted links or bars 71..

J is a post fixed to the center piece of the lower frame to serve as afulcrum for my adjustable beam and lever k, by means of which the upperframe,B, is suspended and operated, and also as a guide to direct themovements of the suspended frame.

I is a projection on the under side and central portion of the beam,that is pivoted in the bifurcated top end of the post J. A series ofperforations, m,in the beam, immediately over the projection l, adaptthe beam to be locked and held stationary on the post at various anglesrelative to the post, as required, to retain the suspended frame atvarious points of elevation relative to the lower frame and the groundnis a bar or link pivoted to the front end and short arm of the lever isand flexibly connected with the frame B, as required, to suspend theupper frame over the lower frame, A, by means of the post J and lever k.

r is an adjustable hook or clevis, pivoted to the front end of the beamk, to serve as a hitching device that can be set and retained at variousangles relative to the beam, by means of a series of perforations, s, inthe beam, and a pin or bolt, as required, to raise and lower the line ofdraft applied to the harrow.

t is a handle pivoted to the rear end of the beam and lever k in such amanner thatit can also be adjusted andfixed to extend at various anglesby means of aseries of perforations, m, in the rear end of the beam, asrequired, to be adapted for men or boys or tall and short persons.

In using my barrow as an attachment to a wheel-cultivator, I hitch it tothe cultivatorcarriage in such a manner that it will drag in rear of andin a central position relative to the two cultivators that advance onopposite sides of a row of plants to loosen the soil and turn it towardthe plants. As my attachment follows the teeth 1 2 3 4, presenting theirsharp edges to the front, will cut through the soil close-to the plantsand loosen and mellow the ground, while the flat plates 0 will press itsmooth, and, in combination with the inclined side bars of the lowerframe, will push clods and rubbish in opposite directions and away fromthe row of plants to deposit the same midway between the rows and out ofthe way.

To raise or lower the suspended frame, as required to regulate the depthof the teeth in the ground, or to clean them by drawing them upwardthrough the perforations 5 6 7 8, I simply adjust the beam and lever Iton the post J.

To use my barrow independently, I attach horses direct to the hitchingdevice 1' at the front end of the beam and then drag it in the mannerharrows are usually operated.

I claim as my invention- The combination of the V-shaped harrowframe A,having metal plates 0, from which extend perforated ears, and avertically-adjustable frame of corresponding l'orm, carrying teeth thatextend through said perforated ears, bearings, and scrapers,substantially as and for the purposes set forth.
